Wavetables do not refresh automatically. Press "Refresh LFO" and/or "Refresh Table" button to apply changes.

CubicPadSynth is a wavetable synthesizer which uses PADsynth algorithm to generate oscillator tables. Cubic interpolation is used to get smooth sound even at inaudible low frequency range:

  • Using PADsynth algorithm for wavetable generation. Providing overtone based interface to manipulate PADsynth profile.
  • A wavetable length is 2^18 samples. Total 136 wavetables are prepared which covers entire MIDI note range (0 to 127).
  • Frequency range is 0 Hz to around 21100 Hz.
  • ADSR envelopes for gain, low-pass filter, pitch.
  • Wavetable based low-pass filter. This filter is not IIR or FIR. Just shifting to the table with less harmonic contents.
  • Tempo synced LFO for pitch modulation. LFO waveform can be directly drawn.
  • Max 128 voices.
  • Max 16 voices for a unison.

This is a very cool synth.

It sounds a bit like a mix of a DX7 and an Additive synth, though it dose not use either method to generate sound.

Very clean in a crystal kind of way, sounds good with chorus verb effects.

Tips:

1. This synth is CPU heavy so consider using arpeggios instead of chords.

2. Some controls are mapped to you QWERTY keyboard, so if you use you computer to play notes, the synth may change parameters instead. So, use a MIDI keyboard, or close the synth window before inputing QUERY notes.

One UI note, would it be possible to make the "Refresh Table" button MIDI mappable?

To GreenOaks, Thanks for the feedback.

From version 0.1.2, refresh buttons are changed from VST message to parameter. So they can be mapped to MIDI. Automation is also enabled, but be careful because refreshing is heavy task.

BarBox control, which has many blue bars inside, is also changed. Now, it's possible to temporarily disable shortcuts when the mouse cursor is on the outside of BarBox.

Linux MINT 19.03 Cinnamom_x64 - Reaper 6.05.

Hi, .

I would like to try all your plugins but I don't understand why Reaper 6.05 don't see them....

Where I puts the.so file? (ONLY the .so file, right?).

Thanks again.

Hi, Codesound.

A VST 3 plugin is a directory, not just a .so file. For example, try copying 'CubicPadSynth.vst3' directory into '$HOME/.vst3'. More information about installation is available on manual page.

If you tried all steps on manual page and still have problem, please let me know. I'll look into it.

Hi, .

Thanks for your clarifications.... also Mint need the install of.

sudo apt install libxcb-cursor0 libxkbcommon-x11-0.

Now all your beautiful plugins works perfectly! Thanks again.

Hi.

Both FL Studio 20 and Reaper (last) got an error while scanning your plugin. Even after I have installed VC_redist.x64.exe. Windows 7, 64-bit. It's a pity because this synth looks great and inspiring.

Hi, vngrvnd.

You could try latest local build on the link below.

- https://drive.google.com/open?id=1PlthhM4K1Q4LmreE9mCSrPP4ZSel_9DQ

If the latest build doesn't work, I'd like to know the CPU model you are using. CubicPadSynth will not work if CPU does not support AVX or later SIMD instruction set.

You could also build the plugin from source code. Repository and build instruction are on the links below.

- Repository: https://github.com/ryukau/VSTPlugins
- Build instruction: https://github.com/ryukau/VSTPlugins/blob/master/build_instruction.md

If you stuck at building, or build instruction is not clear, feel free to contact me via this thread or email to 'ryukau@gmail.com'.

Still got an error during initialization with the local build, alas.

My CPU is AMD A8-6500. It's quite old but apparently supports AVX, according to Wikipedia and CPU-Z.

As for building from sources, I'm not a developer and never did it before. As I see in the instruction, that needs Visual Studio to be installed. Sorry, I won't do it, VS is huge and completely needless for me.

Thanks for the information. It seems like CPU is not the problem.

Could you try IterativeSinCluster and SyncSawSynth?

If either one is working, I'll consider to make more lighter and portable version of CubicPadSynth.

If both aren't working, then I couldn't solve this issue because I don't have Windows 7 environment. In this case, sorry for inconvenience.

Well, these two initialized and work without any issues.

Thanks for your concern and nice plugins. Hope you will have time and opportunity to fix the problem with CubicPadSynth someday.

Best wishes.

Hi.

I made LightPadSynth (LPS), which is more efficient version of CubicPadSynth (CPS).

I'd like to know if it works on your machine. If I will not get the response, I'll release LPS without further modification to portability.

Download link: https://drive.google.com/open?id=1StEyDs3e9RJ_GFvUO_8qbKGqkZZf3Ewo

For quick comparison, LPS doesn't have pitch modulation. Instead a feedback delay is added for each voice. Wavetable is mostly same, but LPS uses linear interpolation for efficiency.

Hi, ryukau.

I've installed LightPadSynth - it loads and works pretty well on my PC. Tried it with FL and Reaper. Sometimes it has a little glitch with GUI, when it becomes black partly or completely, but it doesn't affect the sound and disappears just when I touch or move plugin's window. As for the rest I didn't notice any issues.

Thanks a lot.

Thanks for testing.

If blackout only occurs on FL, it's likely a bug of FL. In my environment, blackout only occurs on FL. And it's not only with my plugins, but also with VST 3 SDK example plugins. FL developers seems to working on VST 3 issues, so I'm waiting for next update.

If blackout occurs on both reaper and FL, then please let me know. I'll look into the issue.

Yeah, I think that is an FL problem, too. It happens only when FL internal windows overlap the synth. I didn't come across this bug in Reaper.

LightPadSynth is released, so the download link to LPS I posted earlier is disabled.

Changes and fixes to the preview version and released version:

  • Fixed a crash when note frequency is too high.
  • Changed the range of Wavetable->Pitch->Multiply. This change may break patches made for preview version.
